To me, it is additional intermittant fueling at low rpm and steady throttle, due to, I believe, throttle position fueling. Kind of like the PCM is confused on how much fueling you want!
You can accelerate through it or back off. Not an issue above 1800 rpm +/-.

'Marine' - -40* is the reading you get when your IAT reading is no activated. Under light load (low boost), IAT will read 10-30* above ambient, in my experience.

Ok. How do I activate the AIT?
Also, the Boost reads low compared to my analog gauge. Gauge will read 5-6 and the PM will read 0-1.
Any ideas?
Thanks!

Quad just released a update for the Pulse IAT.

Marine

Ok. I will look.
Thanks!

I've seen some discussion about the "new" 1000a and 2000a tunes. Guys are having "surging" problems.
Most of them say that even after switching back to an old tune, that the surging is still there.
You might try going back to one of the original 1000 tunes and see what happens.

I had that same surge until I downloaded the comp tune under beta, surge is gone now although the pedal is jumpy like Smarty on sw9. I can drive around that though, I love the comp tune.

Comp tune was ultra surgy for me, and the 2000 beta tune is pretty bad for me as well. Never had these issues on the old RowJ tunes, but these new ones have a lot more fueling.

Surging is from 1400-1900ish rpm's constant throttle and the truck will start jerking. Cruise or no cruise, surges just the same...

Mine is down, I guess the resistor got a little warm. Now I'm stuck with the Juice w/att. I'm sending it out tomorrow and cant wait to get it back.

I've had pretty good luck running the 3000 beta tune. Runs pretty smooth on my truck. Been running it every since it came out. No problems.

That is exactly how my brothers 98.5 is, but it works great on my truck. His truck has RV275's, fass.

I've had pretty good luck running the adr2000a tune. Although I did notice a shudder around 65mph that wasn't there before with the original 2000 tune. Not a big deal though.

As of today, the "4k test" tune that was released back in April still has the least amount of shudder on my truck. This will be my starting point when the Pulse is unlocked.

I've had zero problems with the buttons, perhaps I was one of the lucky ones?

love my 3000 tune, 0 issues. buttons are 1million percent better since i sent in the pulse for the bigger processor.

I just got that email, and I JUST send my pulse in today, so hopefully I'll have it back within the next 2 weeks!
